Hello
I use a ps3 but I can't see as that should make any difference, so let's get this right you're opening up nautilus double clicking on a file and nothing happens ? I don't want to sound patronising but you've tried right click > open, can you open any files or just certain ones ? I'm not a 100% sure linux likes the ntfs file system (or is it the other way round) read this
viewtopic.php?p=25996#p24048 also you can set to open files with single click in preferences > behavior.
If you're having no joy try thunar file manager I much prefer it to nautilus.
It might be an idea to copy the files to a memory device aswell and also try them on another machine,
